Long-wave infrared (LWIR) imaging is widely used in night vision and thermal target recognition, but often suffers from noise and blurred edges. Here, we present a distributed Bragg reflector–liquid crystal (DBR-LC) framework for reconfigurable optical preprocessing of LWIR images. By combining the angle-dependent phase response of DBRs with the electrically tunable refractive index of an LC cavity, programmable spatial-frequency optical transfer functions are realized through angular-spectrum engineering. The framework enables switchable low-pass, high-pass, band-pass, and band-stop filtering for selective denoising and edge detection within a compact, low-power platform, establishing a foundation for reconfigurable optical computing and intelligent infrared imaging systems.
This publication proposes a definition and a classification of agile software development approaches and analyses ten software development methods that can be characterized as being "agile" against the defined criterion.

The study shows that agile practices improve both informal and formal communication, but indicates that, in larger development situations involving multiple external stakeholders, a mismatch of adequate communication mechanisms can sometimes even hinder the communication.

The results indicate that software engineering work practices are chosen opportunistically, adapted and configured to provide value under the constrains imposed by the startup context.

The perception of the impact of agile methods is predominantly positive, and several challenge areas were discovered, but based on this study, agile methods are here to stay.

Jennifer Neville did not want to go into computer science—but that’s exactly where she landed. Neville discusses the starts and stops that led to her professional sweet spot and her work identifying “surprising failures” making it hard for AI to handle complexity. The post What AI gets wrong and what failure teaches us appeared first on Microsoft Research.
